“…For β unknown, the observed improvement is greater inβ than inλ. Regarding bias, it is known that the MLE of λ and β, from record data, are biased; see Reference [23]. In the case of δ-records our simulations show a small positive bias in the estimations of both parameters.…”

“…The reason for focusing on the Weibull distribution is twofold: First, the model and recently introduced variants are widely used in applications; see References [16,17]. Second, inference for its parameters using records has drawn significant attention in recent years; see References [4,5,[18][19][20][21][22][23][24].In our analysis we consider two cases: known and unknown shape parameter, while the scale parameter is always assumed unknown. According to References [25,26] and [27] (Section 14.2), in many practical problems it is not unreasonable to assume that the shape parameter is known or, at least, it is one among a small number of values.…”

“…Exact joint confidence regions for the parameters are also derived by Asgharzadeh and Abdi (2011), meanwhile Teimouri and Gupta (2012) proposed a confidence interval for nth upper/lower record value. Teimouri and Nadarajah (2013) derived exact expressions for constructing bias corrected MLE's. When the shape parameters of two Weibull distributions are equal, the stress-strength parameter of these distributions has a closed form.…”

“…Nesse sentido, uma correção de vício é proposta para que os EMVs modificados possuam correção de vício de segunda ordem. Esta correção tem sido considerada para outras distribuições por muitos autores (CORDEIRO et al, 1997;LEMONTE, 2011;TEIMOURI;NADARAJAH, 2013;GILES;FENG;GODWIN, 2013;RAMOS;MENEZES;DEY, 2018). Em seguida, são apresentados os EMVs na presença de dados com censura aleatória.…”
